They have always been useful for helping me getting discounts on items i've wanted! Doesn't hurt to have them ready as an extension to your browser! All the 1 star reviews genuinely confuse me. This extension is not made to guarantee you coupons for very specific things you're looking to buy. They have plenty of coupons for thousands of items. You just gotta know what you're looking to buy. It's like those coupons you get at local stores, they aren't made to guarantee you coupons for something very specific that you are looking for. What they do however, is provide you with coupons for many items and you can even see what COUPONS THEY PROVIDE and FOR WHAT ITEMS. So look at the catalog and see if there is anything that INTERESTS YOU.
